Abstract

This document specifies a mechanism for protecting hosts connected to
a broadcast network against rogue DHCPv6 servers. The aforementioned
mechanism is based on DHCPv6 packet-filtering at the layer-2 device
on which the packets are received. The aforementioned mechanism has
been widely deployed in IPv4 networks ('DHCP snooping'), and hence it
is desirable that similar functionality be provided for IPv6
networks.
